Be it known that I, CHARLES. Crmr- MAN, citizen of the United States,residing at Fort Edward, inthe county'of Washington and State of NewYork, have invent-,

ed certain new and useful Improvements in Methods and Apparatus forBurning Heavy with a generating chamber 3 which is coiextensive with thelength of ,the exhaust- Oils in Hydrocarbon Engines, ofwhich' thefollowing is a specification;

car on burners or *mternal combustion ene gines and has particularreference toasystem for supplying a 'carbureted mixture to internalcombustion engines. ,1

This application is, a continuation in part,- of my 'copending aplications, carbureter, Serial No. 368,192, ed March 23, 1920,superheater, Serial No. 368,191',"fi1ed March 23, 1920,'and superheater,Serial No. 420,481 filed October 29, 1920. I

In the present invention, one of the important features resides in thecombination with the carbureter set forth in my application Ser. No.368,192,'and the superheater set forth in my application Ser. No.368,191, of means for separately ,superheating and finally mixing airand steam and supplying the saine to the carbureter while at the sametime admitting, from the cooling system of the engine, a supply of waterwhich is led to a steam generator from which the steam thus formed isfed to the said means.

Another feature of the present invention resides in the arrangementwhereby all of the exhaust gases from the engine are utilized, thusavoiding wasteof thermal energy.

In the drawings:

Figure 1 is a side elevation of the system as applied to a motorvehicle, I

Figure 2 is a side elevation, partly in section, of the automatic waterfeeding means,

Figure 3 is a transverse sectional view through the combined superheaterand mixer supplying the carbureter, and

igure 4 is a transverse sectional view through the superheater employedbetween the carbureter and the engine.

The invention is combined with the usual internal combustion engine A ofthe water jacketed type having the exhaust and intake manifolds 1 and 2respectively, with which are connected the superheater B and carburetinsystem C described and claimed in the applications previously identifiedand which,- therefore,need not beset forthlin deta11 in the; presentspecification. How ever, it should be observed that the super-:

heater B constitutes a means for heating the carbureted zproductdelivered thereto from -the carbureter G. a

The exhaust pipe 1 has cast integral therepipe from the first to thelast cylinder and-receives water from an admission pipe 4 which carriesvalves 5 and 6 placed in ahnement andpconnected byth'e, pipe 7 with sformer-having a threaded stem as indicated at 12-, provided" with ahead13 engaging.

with a fork 14; having a spindle 15 leading to the dash buttonadjustment as indicated at 16, while the spindle 17 of the needle valve11' is connected at 18 with a diaphra m 19 carried in the housing 20bolted toget er at 21 and connected by a nipple 22 and pipe 23 with theintake manifold 2, as shown; a spring 24 normally holding the valve 11on its seat. Stuffing boxes 25 pack the respective valve stems so as toprevent leakage.

In operation, the needle valve 10 is ad-- justed to permit a constantflow of the reuire-d amount of water for maximum con itions and theneedle valve 11 is adjusted by the suction on the diaphragm 19 so thatthe required amount is fed to the steam generator 3 dependent, on thesuction in the inlet manifold 2.

The steam thus generated by contact with the exhaust pipe is then led tothe superheater D by the pipe 26 while air is taken into' thesupcrheater by the pipe 27 throu h the screened opening 28, thesuperheater being of the character shown in m pending application filedMarch 29, 1920, erial No. 420,481. A portion of the exhaust from theengine is taken off at 29 and fed through the superheater B, thencepassing through the pipe 30 to the superheater D and final y erlyproportioned for this purpose.

coil such as is described in my copending application, Ser. No.-368,192, filed March 23, 1920, for a carburetor. The combined area ofthe exhaust outlets above referred to is the equivalent of the outletarea of the original exhaust passage and thus amply provides for takingcare of all of the exhaust gases, the outlet holes 31 being prop- Itwill be seen from the foregoing description, that. the heavyhydrocarbons such as kerosene and the like, fed through the carburetingsystem C, receive a combined mix-- ture of steam and air from thesuperheater D, thus supplying the necessary oxygenand manifold andclosed to the atmosphere, a

water inlet pipe connected to the chamber near its forward end, a steamoutlet pipe connected to the chamber near its rear end,

a valve casing interposed in the .Water pipe,

a housing mounted on said chamber, a diaphragm in said housing, a valveconnected to the diaphragm at one side thereof to extend into saidcasingfor controlling the flow I of water through the Water pipe, intosaid chamber, a 'suction'pipe for attachment to an engine intakemanifold and connected to said housing at the opposite side of thediaphragm, and a second manually operated valve interpo-sedin said.Water pipe for controlling the flow of water to said first mentionedvalve. I

2. The combination with an internal combustion engine, of a carburetersupplying carburetted gas to the engine, acombined superheater and mixerconnected to the primary air intake of the carbureter for heatlng all ofthe primary air supply ofv the carbureter prior to the delivery of suchsupply to the carbureter and mixing said supply with steam,'a steamgenerator heated by the exhaust manifold of the engine and supplying thesuperh'eater with steam, and a superhcater connected with the outlet ofthe carbureter between thecarbureter and engine for heating carburettedproduct.

In testimony whereofI afiix my signature.
